This HT is still in service at my station with no issues - 29 years and counting.
Over the years I have used all of the listed accessories as needed and all have functioned as advertised and still do. Current configuration is for nostalgia: Heathkit HP-1175 , TT 2993, TT 2591 HT with TT 2700 Speaker / Mic, Mirage HT 35 watt 2m amp, Heathkit HM 2141 VHF SWR / PWR Meter, Diamond X50A antenna. Received audio is excellent, audio on the other end is very good per comments from those I QSO with.

Regrets: I did not purchase the TT 2201 Sub-Audible Tone Encoder
* or the TT 2425 30 watt Power Amplifier when they were available.

Technology has rendered this Gem obsolete, but for repeater use if one has installed the TT 2201 Sub-Audible Tone Encoder there are no limits to normal chit chat. Many repeaters in my area do not use tone access in this day of Great Technology i.e.Mt. Mitchell 145.190 minus 600 no tone.- Six to Seven state access, at over 6,600 ft.

What is it worth?

Estimating the value of a rig can be challenging. We collect prices paid by real hams over the years to help you estimate the current value of the Ten-Tec 2591. Just bought or sold this model? Let us know what you traded it for and help other ham operators!
